World Cup 2010: Police and protestors clash outside Durban stadium

Armed riot police have charged into hundreds of stewards at a World Cup stadium in South Africa in an attempt to break up a protest over low wages.

Police appeared to set off two percussive grenades, causing loud bangs, to drive the protesters out of a parking lot under the Moses Mabhida Stadium in Durban hours after Germany beat Australia 4-0 in Group D. Officers also fired tear gas and rubber bullets into the crowd.

At least one woman was injured at the protest.

Witnesses saw about 30 riot police charge into the crowd to drive it out of the stadium. While calm quickly returned to the stadium, some of the security stewards, wearing orange and green jackets, continued milling around outside.

A nearby street was littered with rubbish where the protesters were forced away.

Police were called to the scene after hundreds of angry stewards gathered to complain about their wages.

"We were mounting a peaceful protest because they were not paying us what we expected and we were surprised that the police started charging at us. They fired teargas at us," said one of the workers, Sydney Nzoli.

"We left our homes at seven in the morning and now it is nearly 1 o'clock," said Vincent Mkize. "In the dry run, they didn't want to tell us how much we would get."

Another of the stewards, Fanak Falakhebuengu, told the Associated Press that he had heard they would be paid 1,500 rand ($195) a day but were only getting 190 rand ($25).

"They were supposed to give us 1,500, that's what FIFA told us and they gave us 190. We are working from 12 o'clock until now," said another man who asked not to be named. He ran from police before he could give his name.

FIFA did not immediately respond to calls seeking comment.

The police command set up in Johannesburg for World Cup-related matters had not received an official report.
